Look I'm just as unconvinced this will eventuate as anyone else. Time will tell though what they come up with if anything, my bet is still leaning towards vapourware. But we will see.
As for the video, they shouldn't have shown it. They were pressured into showing more, and they showed that video. I don't even think it was the final version of it. So that's all I was saying, a little slack was in order, rather than a complete hanging.
Though if they had of shown that video and asked for cash, then that's totally different. As it stands now, they have said they wont go to sales until they have completed it and can show it working proper. If they stick to that, then there really isn't a concern. But again, IMO , there is probably more chance than not, this will end up as vapourware
